Background: Dexmedetomidine is selective alpha 2 agonist with sedative sympatholytic, analgesic properties and is used as an anaesthetic adjuvant. We have evaluated the effect of dexmedetomidine on various hemodynamic responses to incidences such as laryngoscopy, endotracheal intubation, exubation and pneumoperitoneum in patients who were undergoing surgeries like laparoscopic cholecystectomy. We have used loading dose of 0.5mcg/kg of inj. Dexmedetomidine given over 10 minutes followed by infusion of a dose of 0.3mcg/kg/hour for the control of hemodynamic response to laparoscopy. Methods: Patient of either sex aged between 18-50 yrs, belongs to ASA I and II (AMERICAN SOCIETY OF ANAESTHESIOLOGY) posted for laparoscopic cholecystectomy were included. Institutional ethical committee clearance was obtained prior to study. After enrolment and valid written consent was taken. 60 patients were enrolled written valid informed consent was taken. Patients were divided into two groups 30 each with computerized randomization. Base line parameters were noted. Observer and patient was blinded for the content of syringe. Group A received injection dexmedetomidine and group B received bolus and infusion of normal saline at same rate. Routine general anaesthesia was instituted. Parameters were noted after induction, after intubation, after co2 insufflation, after 20 min, after 40 min, after co2 deflation, after extubation, after 1 and 2 hrs post-extubation. Results: Group A showed significantly less rise in HR and MAP than Group B. Requirement of intraoperative propofol was more in Group B. There was no significant difference for time taken to awakening in both groups. Conclusion: We found Injection Dexmedetomidine in given doses gave good hemodynamic control with minimal undesired effects during laparoscopy.

Introduction: Laparoscopy is a widely performed minimal invasive surgical procedure, wherein various haemodynamic changes are faced by anaesthesiologists during Pneumoperitoneum (PNP). Aim: To compare the effectiveness of dexmedetomidine vs fentanyl for attenuating the haemodynamics response to PNP in Laparoscopic Cholecystectomy (LC). Materials and Methods: A total of 84 patients of 18-50 years age, American Society of Anaesthesiologists (ASA) Class I/II of either sex for elective LC were included. The patients were divided into two groups (A, B) of 42 patients each. Group A received dexmedetomidine and Group B received fentanyl. Both the drugs were given as loading dose of one μg/kg over ten min followed by maintenance 0.2 μg/kg/h throughout the surgery. Haemodynamic parameters were recorded at different time intervals throughout the surgery. In recovery room patients were observed for postoperative analgesia by using Visual Analogue Scale (VAS), sedation level using RAMSAY Sedation score at every 30 minutes till the time of giving first rescue analgesia and side effects, if any. Results: Intraoperatively, throughout the period of PNP, Group A showed statistically better attenuation of haemodynamic responses in comparison to Group B (p<0.05). After creating PNP, rise in Mean Arterial Pressure (MAP) was observed in both group A and group B, 99.38±6.32 and 103.43±9.81, respectively but this rise was more in group B which was statistically significant (p<0.05) throughout the surgery except 40 minutes after PNP creation. Time to first rescue analgesia or mean duration of postoperative analgesia (VAS>3) was significantly longer in dexmedetomidine group (102.14±32.50 minutes) than fentanyl group (42.86±15.03 minutes). There was better control of pain but more sedation in Group A than in Group B. Conclusion: This study concludes that intravenously administered dexmedetomidine shows better attenuation of haemodynamic responses to CO2 insufflation as compared to fentanyl. Dexmedetomidine also provides better sedation and has more analgesic sparing effect.

The present study was done to evaluate the ability of oral pregabalin to attenuate the pressor response to airway instrumentation in patients undergoing laparoscopic cholecystectomy under general anesthesia. Sixty-four adult patients aged between 25-55 year of either gender belonging to ASA-1 or ASA2 physical status weighing 50-70 kg were enrolled in this study. Thirty-two patients each were randomized to group A, or group B. Patients in group A received tablet Pregabalin (150mg) and those in group B received placebo orally one hour before induction of anaesthesia. Heart rate, blood pressure, and sedation were assessed preoperatively before giving the tablets and after 30 minutes, and just before induction of anaesthesia. Intraoperative, pulse rate, mean arterial pressure, ECG in the lead II, SPO2 and ETCO2 were monitored. All the above parameters were noted during laryngoscopy and intubation, 3 minutes after CO2 insufflation, and then at every 10-minute interval till the end of surgery. These parameters were also recorded after extubating the patient. The Ramsay sedation scale was used to assess the sedation at the baseline, one hour after drug intake , one hour after extubation and 4 hour after surgery. Any adverse effects in the postoperative period were recorded. The result of our study shows that pre-emptive administration of oral pregabalin 150 mg significantly reduced the pressor response at the time of laryngoscopy and intubation, after CO2 insufflation and just after extubation. We conclude that oral pregabalin premedication is effective in successful attenuation of hemodynamic pressor response to laryngoscopy, intubation and pneumoperitoneum in patients undergoing laparoscopic cholecystectomy

Summary Many of the children referred to the emergency complain of head trauma. Children usually require sedition to reduce their failure and fear because of high activity and fear of performing computed tomography (CT). Dexmedetomidine and Midazolam belong to short-acting drugs for this purpose. This study aimed to compare the effect of the above mentioned drugs on sedition in children. Children referred to the emergency department were randomly divided into two groups. Group A was sedated with 0.05 mg/kg IV Midazolam and group B with 2μg/kg IV Dexmedetomidine over 10 minutes (loading dose), and then repeat boluses 2μg/kg IV over 10 minutes. Measurements included induction time, recovery time, efficacy, side effects, complications, and failure with each drug and vital signs and RAMSY scale. SPSS V.20 was used for data analysis. p<0.05 was considered statistically significant. Totally, 100 patients participated in the current study (44 girls and 56 boys). The mean and standard deviation of age was 5.3 ± 2.5 years. During the study, just 5 patients (10%) from group A did not have appropriate sedition following the injection of first dose of Midazolam and received the second dose. However, in B group patients no such case was reported. No significant difference was observed among blood pressure, heart rate, respiration and RAMSY Scale among the groups. No significant difference was seen between efficacy of Midazolam and Dexmedetomidine in pediatric sedation. More research should be done for generalization of our findings .

Proton pump inhibitors are widely used for Gastro Esophageal Reflux Disease (GERD) treatment. This prospective double blind randomized cross over study was carried out in the Department of Gastroenterology, BSMMU from June 2007 to May 2008 to assess the efficacy of Immediate-release omeprazole (IR-OMEP) & Delayed-release Omeprazole (DR-OMEP) in relieving symptoms & healing of oesophagitis in GERD. All patients who fulfilled the inclusion criteria underwent upper gastrointestinal (UGI) endoscopy to be lebelled as nonerosive and erosive GERD. Among total 69 patients, 43 (62.3 %) had nonerosive and 26 (37.7 %) had erosive GERD. Patients were divided into group A (35) and group B (34) who received group A drugs (20 mg IR-OMEP bd) and group B drugs (20 mg DROMEP bd) from day 1-14 respectively. Then drugs were crossed over (group A: 20mg DR-OMEP bd; group B: 20 mg IR-OMEP bd) from day 15-28. Improvement of heartburn, regurgitation in each group were assessed in every week, during drug cross over and at the end and then compared between two groups. There was no significant difference in relieving heartburn and regurgitation between IR-OMEP and DR-OMEP either in erosive or nonerosive GERD (P>0.50). Patients with erosive GERD underwent UGI endoscopy at the end of treatment to see healing of esophagitis. Study showed significant healing of oesophagitis in group A after 4 weeks than group B (14%) (P<0.05) but there is no superiority of IR-OMEP over DR-OMEP in relieving symptoms of GERD.Faridpur Med.

Background: Standard four port laparoscopic cholecystectomy is the gold standard in the treatment of gall stones. Modified epigastric port laparoscopic cholecystectomy may be considered an alternative, as this procedure maintains the advantages of four ports and does not require any special set of instruments. In this study we aimed to see whether this procedure is comparable to the standard four port laparoscopic cholecystectomy based on the primary objectives of postoperative pain score, degree of ambulation, time to return to normal activities.Methods: Consecutive patients due to undergo laparoscopic cholecystectomy, meeting all the predefined criteria were recruited into the study. The group A was assigned to receive intervention in the form of modified epigastric port laparoscopic cholecystectomy. The group B was assigned to receive intervention in the form of standard four port laparoscopic cholecystectomy. Patients in group A were compared with patients in group B based on multiple pre-defined parameters.Results: Pain scores were significantly better in group A. Degree of ambulation at was significantly better in group A. In respect to the time to resumption of normal activities there was no significant difference between the two groups. When comparing the quality life at 1 month following surgery with SF-36 health survey, the patients in group A did better than patients in group B with respect to the six scales. Conclusions: Modified epigastric port laparoscopic cholecystectomy appears to be significantly better than the standard four port cholecystectomy in terms of postoperative recovery.

ABSTRACT Background: Elective laparoscopic cholecystectomy has very low risk for infectious complications, ranging the infection rate from 0.4% to 1.1%. Many surgeons still use routine antibiotic prophylaxis Aim: Evaluate the real impact of antibiotic prophylaxis in elective laparoscopic cholecystectomies in low risk patients. Method: Prospective, randomized and double-blind study. Were evaluated 100 patients that underwent elective laparoscopic cholecystectomy divided in two groups: group A (n=50), patients that received prophylaxis using intravenous Cephazolin (2 g) during anesthetic induction and group B (n=50), patients that didn't receive any antibiotic prophylaxis. The outcome evaluated were infeccious complications at surgical site. The patients were reviewed seven and 30 days after surgery. Results: There was incidence of 2% in infection complications in group A and 2% in group B. There was no statistical significant difference of infectious complications (p=0,05) between the groups. The groups were homogeneous and comparable. Conclusion: The use of the antibiotic prophylaxis in laparoscopic cholecystectomy in low risk patients doesn't provide any significant benefit in the decrease of surgical wound infection.

Abstract Background Muscle relaxants used in general anesthesia during the insertion of an endotracheal tube (ETT) to relax the muscles of the neck and throat, which reduces the risk of injury. They also are used to relax the chest muscles when an endotracheal tube is used to aid mechanical ventilation. Objective The aim of this study has been to evaluate the effect of calcium chloride coadministered with neostigmine and atropine on neuromuscular blockade recovery time at the end of general anesthesia. And compare it’s effect against usual neuromuscular reverse of neostigmine and atropine. Patients and Methods In this present study we use Double blind prospective randomized Clinical trial study, 30 patients were enrolled. They were divided in two groups each of which contains 15 patients: Group (A): received 5 mg/kg of calcium chloride coadministered with 25 μg/kg of neostigmine and 15 μg/kg of atropine at the end of surgery. Group (B): received the same volume of normal saline coadministered with 25 μg kg of neostigmine and 15 μg / kg of atropine at the end of surgery. Results Comparison between calcium and neostigmine groups according TOF at 5 minutes and 10 minutes using Independent t-test, P- value was less than 0.01 which means that there is high significant difference between 2 groups. On the other hand, TOF at 20 minutes in calcium and neostigmine groups shows no difference at all. Conclusion So Calcium chloride elevate serum calcium level, calcium has antineuromuscular blockade effect, therefore calcium chloride increase TOF and enhance neuromuscular recovery and decrease the PORC after neostigmine administration.

Background: The physiological consequences of post-operative pain including Stress response to surgery, Respiratory complications, cardiovascular complications, Thromboembolic complications, Gastrointestinal complications, Musculoskeletal complications and Psychological complications, all of which could delay or impair postoperative recovery and increase the economic cost of surgery as a result of the longer period of hospitalization. Inadequate post-operative pain control may also lead to the development of chronic pain after surgery .Aim of This study: is to evaluate the preemptive analgesic effect of intravenous ketamine in laparoscopic cholecystectomy. Patients and Methods: double blinded randomized clinical trial conducted at Al-Yarmouk teaching hospital, over a period of one year from March 2013 to March 2014 on a total of 120 adult patients scheduled for elective laparoscopic cholecystectomy, Patients were divided in to three groups of 40 patients each, the study drug administered intravenously during induction. Groups A and B received ketamine in a dose of 1 and 0.5 mg/kg, respectively, whereas group C received isotonic saline. The degree of pain at rest and deep breathing postoperatively were estimated using VAS, time of first analgesic dose, total opioid consumption, nausea, vomiting and hallucination were recorded for 24 h postoperatively. Results: postoperative pain scores were significantly low in group A when compared with the other groups at most times in the first 24 hours. Highest pain score was in group C at 0 h. Postoperative analgesic consumption was minimum in group A then group B and highest in group C. There was little significant difference in the pain scores between groups B and C. Group A had a significantly higher blood MAP than group B at 0, 0.5 and 1 h. 7.5% incidence of hallucinations were in group A. Conclusion: According to this study we conclude that preemptive ketamine in a dose of 1 mg/kg has a definitive role in reducing postoperative pain and analgesic requirement in patients undergoing laparoscopic cholecystectomy. A low dose of 0.5 mg/kg had little significant in preemptive analgesic effect and in reducing analgesic requirement.
